An update for zstd is now available for openEuler-20.03-LTS and openEuler-20.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1094 Final 1.0 1.0 2021-03-26 Initial 2021-03-26 2021-03-26 openEuler SA Tool V1.0 2021-03-26 zstd security update An update for zstd is now available for openEuler-20.03-LTS and openEuler-20.03-LTS-SP1. Zstd is a fast lossless compression algorithm. It's backed by a very fast entropy stage, provided by Huff0 and FSE library. It's a real-time compression scenario for zlib levels and has a better compression ratio. Security Fix(es): Beginning in v1.4.1 and prior to v1.4.9, due to an incomplete fix for CVE-2021-24031, the Zstandard command-line utility created output files with default permissions and restricted those permissions immediately afterwards. Output files could therefore momentarily be readable or writable to unintended parties.(CVE-2021-24032) An update for zstd is now available for openEuler-20.03-LTS and openEuler-20.03-LTS-SP1. openEuler Security has rated this update as having a security impact of critical. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
